Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple machine learning techniques are combined to analyze crime data and generate patrol routes, then the accuracy of crime prediction and hotspot identification is improved, but the system complexity increases
Solution Approach 1:
The patent segments the crime analysis process into distinct functional modules: crime data clustering module, hotspot identification module, prediction model module, and patrol route generation module. Each module performs a specific task using appropriate machine learning techniques, making the complex system manageable and maintainable while achieving high prediction accuracy through specialized processing at each stage.
Solution Approach 2:
The patent combines multiple machine learning techniques (clustering algorithms, kernel density estimation, regression analysis, and optimization algorithms) into an integrated system that processes crime data comprehensively. By merging these different analytical approaches, the system achieves superior crime prediction accuracy and hotspot identification capability that would be difficult to attain with a single technique.
2Reliability
If patrol routes are generated based on comprehensive spatio-temporal crime data analysis, then the effectiveness of preventive surveillance is improved, but the time required for route generation increases
Solution Approach 1:
The patent performs preliminary analysis of crime data to pre-identify hotspots and predict future crime locations before generating patrol routes. By pre-processing the crime data and establishing prediction models in advance, the system reduces the time required for real-time route generation while maintaining high preventive surveillance effectiveness based on accurate crime predictions.
Solution Approach 2:
The patent replaces manual patrol route planning with an automated computer-based system that uses machine learning algorithms to analyze crime data and generate optimized routes. This substitution of mechanical/manual processes with automated computational methods dramatically reduces route generation time while improving the reliability of preventive surveillance through data-driven decision making.
3Ease of operation
If security officers patrol based on traditional methods without utilizing spatio-temporal crime data, then the operational simplicity is maintained, but the productivity and crime prevention capability decrease
Solution Approach 1:
The patent implements a system where security officers use mobile devices to receive automatically generated patrol routes based on crime data analysis. The system serves itself by continuously analyzing crime data, updating hotspot predictions, and regenerating optimized routes without requiring manual intervention from officers, thereby maintaining operational simplicity while dramatically improving crime prevention efficiency through intelligent, data-driven routing.

AI summary
For the purpose of improving safety in cities and reducing the number of crimes, this research proposes an algorithm which combines artificial intelligence (AI) and machine learning (ML) techniques to generate police patrol routes. The invention consists of four steps and combines spatial and temporal information. First, crime data is clustered by applying K-means, then crime hotspots are considered by applying KDE and future critical spots are predicted using linear regression. In addition, the probability of crimes being committed in a given area according to a time zone is studied. This information is combined to obtain real surveillance routes in the area through a fuzzy logic decision system. The results prove that the use of spatio-temporal information allows designing surveillance routes in a way that increases their effectiveness, and therefore public safety, and reduces expenditure on police resources.
